  • Patent number: 11982421
    Abstract: A retractable spotlight comprises a cylindrical outer casing and a lamp body movably supported inside the outer casing. A pressing assembly and a connecting assembly are disposed inside the outer casing. The pressing assembly biases the lamp body towards an extended position via the connecting assembly and is configured to be switched between a first position, in which the lamp body is in a retracted state, and a second position, in which the lamp body is in the extended state. The lamp body is rotatably connected to the connecting rod via a radial articulated shaft. The state of the lamp can be adjusted by pressing an automatic locking feature and manually pushing and pulling the lamp body, thereby increasing the versatility of single lamp adjustment while preventing excessive loads on the wire.
